SPECIFICATION" forming part of Letters Patent No. 530,663, dated December 1 1, 1894.

Application filed nmi 20, 1894. Serial No. 497,644- (No model.)

To all whom it may, concern: I

Be it known that I, ALBERT O. SHAW, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Faucets; and I hereby declare the following to be a full,clear, and exact description of the same.

My invention relates to a novel construetion of faucets which are especially adapted for use in conjunction with vessels containing an eifervescent or gas saturated liquid.

My invention consists of the construction and combination of devices which I shall hereinafter fully describe and claim.

Referring tothe accompanying drawings for a more complete explanation of my invention, Figure 1 is a side view and partial section of the faucet and attachments. Fig. 2 is a separate view of the valve. Fig. 3 is a general view showing the apparatus and faucet connections.

Efiervescent liquids, such as soda water, beer, &c., depend for their value upon the amount of carbonic acid gas which is held in solution in the liquid under considerable pressure. This gas escapes rapidly when the liquid is drawn and often to such an extent as to leave the liquid fiat and of little value, before the cask or vessel is entirely emptied. It has been customary in many cases to put a pressure upon the liquid by pumping air into the vessel, but this deteriorates such liquids as beer by furnishing oxygen which soon causes the beer to acidify or otherwise lose its quality. I

My invention is designed to enable the user to supply the carbonic acid gas to the beer to any desired extent, and to render the liquid in all respects equal to that which. is drawn when the cask is first opened. In order to do this, it is customary to supply carbonic acid gas under high pressure in containing cylinders A provided with suitable valve and con nections, and these cylinders which are filled at'a central station are sent to the various places where they are to be used, and kept in readiness for this purpose.

B is a pipe connecting the vessel A with the faucet having a suitable connection at C'. I D is the faucet having the usual central passage E through which the liquid is drawn from the cask, the faucetbeing driven or otherwise securedi'n the cask in any usual sage E is thickened sufficiently to allow a,

small passage F to extend approximately parallel with the passage E from the inner end ofthe faucet to a chamber G which is formed upon the faucet barrel, and with which chamber the passage F connects as shown.

The coupling or. connection 0 with which the pipe B unites, is adapted to screw into the top of the chamber G so as to make a tight joint. within the chamber G, has attached to it a flexible hollow cylindrical valve H, the lower end of which is made conical as shown at I. This conical end has a slit J made to extend across the apex of the cone and approximately from one sideto the other of the diameter thereof.

When, for any reason, the pressure within the cask has become reduced too low, and it is desired to again increase it, it is done by opening the valve connecting with the receiver A, and the gas is allowed to flowthrough the pipe B and the coupling C into the interior of the valve I. The pressure thus exerted opens the slit J, allows the gas to flow into the lower part of the chamber G and thence through the passage F into the cask or receptacle. The gas thus delivered into the lower part of the receptacle, rises through the liquid and thus agitates' it, so that the gas is more readily absorbed by the liquid than if delivered into the upper part of the cask. The absorption of the gas is assisted, if desired, by still further agitating the cask by means of a rocking frame upon which it may be supported,- so that the liquid will become fully charged with the gas and in every respect become rejuvenated, and of a quality equal to that when it was first opened.

The amount of pressure admitted to the cask is determined by means of a pressure gage K upon the pipe B. When this gage indicates a sufficient pressure within the cask, the valve of the receiver A is closed, and the peculiar shape and conical bottom of the valve I is such that the pressure from the cask acting upon the cone, closes the slit J hermetically, and prevents any return of gas,

- The lower part of thisscrew cap or liquid even although the pressure in the pipe B should be entirely removed. When the liquid is to be drawn directly from the cask the key L is turned, and the lower end of this key has an opening through which the liquid is discharged in the usual manner. In many cases, however, it is desirable to keep the cask in a basement or cellar or in some other cool place, while the liquid is to be drawn for use at a point distant from this place. In such 'case it is necessary to connect a conducting pipe with the faucet, and this is done in the following manner: The nuts M, which are screwed on to the lower end of the key to retain it in place, fit .into a chambered extension N which extends downward from that portion of the faucet, and

this extension is screw-threaded upon the outside as shown. The lower end of the ex tension is approximately flush with the bottom of the lower nut, and a washer may be placed at this point surrounding the discharge end of the key L.

O is the connection for the delivery pipe P which is to convey the liquid to a distant point. The upper end of this extension has formed upon it a flange Q which fits against a washer at the lower end of the part N so as to make a tight joint at this point, and the discharge end of the keyL enters the extension 0 as shown.

B is a nut preferably having arms orex tensions by which it is easily turned by hand. This nut is threaded to flt the exterior of the part N upon which it is screwed. The lower end of the nut has an inwardly projecting flange, as shown at S, which is of less diame ter than the flange Q of the connection 0 so that when the nut is screwed up into place the flange S forces the flange Q closely against the lower end of the part N, and thus makes a tight joint at this point. The key L being then turned so as to open communication with the cask or receptacle, the liquid will flow freely through it and into the pipeP by which it is conveyed to the point where the liquid is to be delivered.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

In a faucet, the combination, of the barrel thereof having a main discharge passage and a chambered extension provided with exterior threads, the nuts fitted in said chamber, the connection 0 for the delivery pipe, having a flange at its upper end adapted to fit under the lower end of said chamber and to make a tight joint therewith, and a handled nut threaded upon the exterior of the exten sion of the faucet and having a flange Q at its IOWGJ end adapted to pass under the flange of the connection 0 whereby when the nut is screwed into place the flange thereof forces the flange Q closely against the chamber and forms a tight joint.

In witness whereof I have hereunto set my hand.

ALBERT C. SHAW.
